Title: Multichannel type head
Inventor: NAITO SAISHI
IPC: G06K7/08
Filed: 1988-03-11
Abstract: Sensors are widely used to read magnetic data and to read the magnetic and the optical patterns printed on notes and so on. Since this invention multichannel type head has plural magnetic cores (11-19) arranged in a row and a cancellation core (20) for noise removal, the head can detect magnetic characteristics as a whole in a stationary state without depending on the relative speed of the magnetic member with the head, and therefore is least affected by noises. Since one cancellation core is shared by plural magnetic cores, the structure as a whole becomes simple, and the manufacture cost can be remarkably reduced. Since a magnetic head is combined with optical fibers in an integral structure according to this invention, it can read the magnetic patterns and the optical patterns on the same location simultaneously by a parallel operation.

Abstract: Optionally N-protected peptides, especially dipeptides, are obtained by continuous enzymatic reaction of N-protected amino-acid alkyl esters in the presence of serine protease or peptidase, especially carboxypeptidases, in aqueous phase with exclusion of organic solubilisers and with retention of the enzyme in the reaction chamber with an excess of free amino acid (molar ratio > 50 : 1) and a residence time such that there is quantitative conversion of the ester into the N-protected peptide which is removed from the reaction mixture leaving the reaction chamber by adsorption on a hydrophobic adsorber, while the remainder of the reaction mixture containing the amino acid is returned to the reaction chamber. The N-protected peptide is eluted from the adsorber with aqueous solution and then deacylated enzymatically. Formation of peptide and elimination of protective groups are preferably carried out in an enzyme membrane reactor or with enzyme immobilised on a carrier. Used as N-protected amino acid ester is, in particular, N-phenylacetylamino-acid alkyl ester whose protective group is eliminated enzymatically using penicillin-G acylase. Reaction of N-protected aromatic amino-acid ester with free aliphatic amino acid has been particularly investigated (in particular formation of TyrAla).
